Problems solved by technology

[0003] The existing sand barriers include straw sand barriers, clay sand barriers, nylon net sand barriers, etc. These sand barriers have played some roles in the process of preventing and controlling quicksand, but they have high cost, affect environmental protection, poor effect, and short warranty period and other issues, therefore, desertification prevention and control technology still needs to be improved

specific Embodiment 1

[0034] like figure 1 As shown, a sand barrier structure includes a first sand layer 1 arranged on the outer surface, a second sand layer 3 arranged at the bottom, and a clay layer 2 between the first sand layer 1 and the second sand layer 3,

[0035] The thickness of the first sand layer 1 is 30cm,

[0036] The thickness of clay layer 2 is 20cm,

[0037] The first sand layer 1 is aeolian sandy soil, and its texture belongs to sandy soil in the international soil classification system.

[0038] The second sand layer 3 is aeolian sandy soil, and its texture belongs to sandy soil in the international soil classification system.

[0039] The clay in the clay layer 2 is a loamy soil with a tighter structure than the sandy soil in the International Soil Classification.

[0040] Further, the width of the first sand layer 1 is 1 meter, and the width of the clay layer 2 is 1 meter.

[0041] like figure 2 Shown, a kind of preparation method of sand barrier structure comprises the ...

specific Embodiment 2

[0049] It is roughly the same as the specific embodiment 1, the only difference is that the texture of the clay layer 2 is clay, and the clay is a clay loam soil with a tighter structure than the sandy soil in the international soil classification system.

specific Embodiment 3

[0050] It is roughly the same as the specific embodiment 1, except that the texture of the clay layer 2 is clay, and the clay is a clay with a tighter structure than the sandy soil in the international soil classification system.

Abstract

The invention relates to a sand barrier structure and a preparation method thereof. The sand barrier structure comprises a first sand layer arranged on the outer surface, a second sand layer arranged at the bottom, and a clay layer positioned between the first sand layer and the second sand layer. The preparation method of the sand barrier structure comprises the following steps: (1) clay is smashed for future use; (2) the construction is performed from the bottom of a sand dune in a 1 m belt-shaped manner to divide the sand dune into a first sand belt, a second sand belt, a third sand belt and a fourth sand belt; and then, the clay with a thickness of 20 cm is flatly paved on the quicksand surface of the first sand belt; (3) aeolian sandy soil is taken from the second sand belt to flatly pave on the upper surface of the clay of the first sand belt to form a first sand layer with a thickness of 30 cm; (4) the clay with a thickness of 20 cm is flatly paved on the second sand belt; and then, aeolian sandy soil is taken from the third sand belt to flatly pave on the upper surface of the clay of the second sand belt; and (5) like this, the clay and the aeolian sandy soil are paved on all the sand belts.

Description

technical field [0001] The invention belongs to the technical field of sand prevention and control, and in particular relates to a sand barrier structure and a preparation method thereof. Background technique [0002] Drift sand control technologies are mainly divided into mechanical sand barrier control technology, chemical sand control technology and biological sand control technology. The control of quicksand firstly prevents the movement of quicksand, and then carries out biological sand control. [0003] The existing sand barriers include straw sand barriers, clay sand barriers, nylon net sand barriers, etc. These sand barriers have played some roles in the process of preventing and controlling quicksand, but they have high cost, affect environmental protection, poor effect, and short warranty period Therefore, desertification prevention and control technology still needs to be improved.
